I've had a similar problem in the past.

With my machine it was a dirty belt and drive wheel, I gave it a really good clean.

I can't officially answer that as I am not qualified - the water does not come into contact with the electrodes unless something goes wrong - that's the time it matters and I play on the safe side. I had a tube which I had a build up of scum in the output coupler which reduced the flow until it ove...

I don't see any build up in my tube, perhaps my tap water is soft enough.

The conductive thing, is there any conducting going on in the water? or is that a safety issue?

The other day my new tube died, 1 month old, air bubble - disaster. So I went back to an old tube that I had cutting at a very slow rate, as i didn't have a spare in stock. I mainly cut 3mm MDF and my setting for a new tube are approx. 17mm at 85% power (40W tube) As the tube gets older I reduce the...

I just use tap water.

Do I really need to use distilled water, whats the advantage?

We've started having communication problems Laser cutter to PC. I get the following error very often (almost every time) "The communication is broken for timeout. Please close and open the output window to retry" The only way to get it going again it to reboot the Laser cutter, and sometim...

Yes, at the anode.

My tube was arcing, at the positive connection

I have fixed it with silicon sealant, will it of done any damage to the PSU or tube?

Cutting is a bit less efficent than a couple of days ago, but my tube is getting old so it could just be that

Thanks

I think I should be able to knock something together to globally change the project file (ECP), if I do I will post it.

I've got an old tube and I want to check a few things, find out what others do. Q1) Does an old tube start giving out less power across its range or just at the top end? Mine seems to be top end only, but I have no power meter Q2) I cut MDF and the machine gets pretty dirty, and I want to check I'm ...
